ISO stands for International Standards Organisation, it comes from when the sensitivity of films became standardised. It refers to the speed that your camera responds to light. The higher the ISO number the more sensitive the film or digital sensor is to light. If you choose to use a lower ISO(lower sensitivity) setting you will have to have a longer exposure, this is known as slow film. Fast film is when you have a higher sensitivity and a faster exposure. A higher ISO setting allows a faster shutter speed with the same aperture setting, this means the picture will have less Blur. The downside it that the Higher the ISO the more noise (or grain) your image has.

What is the iso code?
The International Standards Organisation code (ISO) was developed to consolidate the ASA/DIN system to rate the relative speed of various films. ISO 400 film is faster than ISO 100 film, for example, making it better for low-light or fast action photos
What standards agencies are responsible for the OSI standards architecture?
The standards agencies responsible for the OSI standards architecture are the International Organization for Standardization (ISO) and the International Telecommunications Union-Telecommunications Standards Sector
What does the ISO or ASA of a film indicate?
ASA acronym for American Standards Association - hence ASA400 on films is the standard film speed of 400. ISO is International Standards Organization. the two values are identical, for once there is no separate ( Metric) or different European film standard. The Germans do use the DIN ( German Industrial Norms) standards this is such that that- DIN 27 is equivalent to ASA 400. ASA and DIN are the only common film standards used today. There you have it. Get yourself a Photometer and the meanings of the various scales will be self-evident. Besides you can learn much about differing exposure values- for nearly every potential shot there are more than one possible (answers) so there are considerable variables around. Experiment!
Why is ISO so important in photography?
It's a rating for the sensitivity of the film to light. The higher the number, the more sensitive. For digital, it represents a corresponding increase in the sensitivity of the ccd (the image capturing device). Either way, higher numbers trade off image quality for speed.
What is ISO range?
An ISO range is how much a camera can electronically brighten a photo. It can be anywhere from 80 all the way up to 12,800. The only problem with higher ISO is the fact that when you use higher ISO it creates noise in the image making the quality of the photo deteriorate.
